According to this example, as shown in Figure 3, luminescence unit 30 is accommodated in tubular outer cover 20 to be positioned at than more leaning on the mode of the position of downside with the center 47 of the section of the length direction quadrature of tubular outer cover 20.By this, divide, make the internal volume of receiving space 24A of lampshade portion 22 sides of tubular outer cover 20 greater than the internal volume of the receiving space 24B of light-projecting portion 21 sides by luminescence unit 30.Therefore; The thermal capacity of the receiving space 24A of lampshade portion 22 sides is also bigger; Owing to carry out sufficient convection current, so can come to dispel the heat well by heat exchange action, this heat exchange action utilizes the outer surface of lampshade portion 22 that heat is derived from the box body (case) of heat sink 31 or ignition device 40.Again, the OPTICAL SENSORS (sensor) that brightness is on every side detected is equipped on and is equipped with the opposite another side side of one side side of the heat sink 31 of luminescence unit 30.
On the other hand; The receiving space 24B of light-projecting portion 21 sides relatively narrows down; Be installed on the light-emitting substrate 32 of luminescence unit 30 light emitting diode 33, and the light-projecting portion 21 of tubular outer cover 20 between distance shorten, thereby can obtain following optical characteristics: the irradiation of the direction towards expection from light-projecting portion 21 effectively of the radiating light of luminescence unit 30.For the distance between the light-projecting portion 21 of the light emitting diode 33 of luminescence unit 30 and tubular outer cover 20, preferable maintenance can not make from the emergent light of light-projecting portion 21 produce the degree of dazzle (glare) distance, and can not make the distance that produces the degree of granular sensations as the light emitting diode 33 of light source.
Again; The side edge part of heat sink 31 carries and places a pair of slot part 32 and be installed with; The side edge part of this heat sink 31 is configured to towards giving prominence to than the outer peripheral face more lateral of the light-projecting portion 21 of tubular outer cover 20, and by this, light-projecting portion 21 sides and lampshade portion 22 sides are blocked in fact; Therefore, come the light of the light emitting diode 33 of selfluminous cell 30 can not enter to the receiving space 24A of lampshade portion 22 sides of tubular outer cover 20.Therefore, because OPTICAL SENSORS can not receive the influence of the light of light emitting diode 33, so can prevent the misoperation of OPTICAL SENSORS, and can prevent light evil (light pollution)
Again, as stated, with the mode of top 28 sides towards the top; By the bend 55 of arm 50, make the long axis direction inclination of tubular outer cover 20 and be installed on the body of rod, particularly; Be set to be inclined relative to horizontal about 20 °～50 °, be preferably 25 °～40 °.
Figure 12 is when lighting device 10 is installed on the installation body of rod of A position; Be contained in the Illumination Distribution figure of the luminescence unit 30 of tubular outer cover 20; Figure 12 A is the Illumination Distribution figure of the angle of luminescence unit 30 when with respect to the horizontal plane being 0 °; Figure 12 B is the Illumination Distribution figure of the angle of luminescence unit 30 when with respect to the horizontal plane being 25 °, and Figure 12 C is the Illumination Distribution figure of the angle of luminescence unit 30 when with respect to the horizontal plane being 55 °.
In Figure 12, luminescence unit 30 is 4.5m with road surface (shadow surface) height apart, and road width is 5m, and the configuration space of lighting device (criminal's of preventing lamp) 10 is 10m, and has represented and the Illumination Distribution face of road surface on the ground at a distance of the shadow surface of 1.5m.Because adjacent mounting rod body is positioned at the B position, so can be overlapped in and the shadow surface of road surface at a distance of 1.5m from the emergent light of adjacent lighting device 10.
After changing angle and Illumination Distribution illustrated in fig. 12 being measured; Confirm: in order to obtain and the high evenness of road surface at a distance of the shadow surface of 1.5m; Luminescence unit 30 is set to be inclined relative to horizontal about 20 °～50 °, and preferable inclination gets final product for 25 °～40 °.
According to example of the present invention; Because lid 60 is disposed at than more leaning on the position of downside with the center of the section of the length direction quadrature of tubular outer cover 20; So being installed on the light of light emitting diode 33 towards the top of the one side side of light-emitting substrate 32 certainly is suppressed; Obtain the effect of light evil countermeasure, can reduce the temperature of luminescence unit 30.Again, owing to can reduce the loss (loss) of optics control, and the OPTICAL SENSORS of perceived illumination intensity that is arranged at the another side side of light-emitting substrate 32 can not receive the influence of the light of light emitting diode 33, therefore, can prevent the misoperation of OPTICAL SENSORS.Because luminescence unit 30 is set to be inclined relative to horizontal about 20 °～50 °, therefore, can suppress the brightness of road transverse direction and the gradient of illumination again; Obtain high evenness, again, because opening is in downside; That is, be arranged in gravity direction, so also can suppress the intrusion of rain etc.
